Lord Winston plumped the feathers of hungover brokers at Biba with a rousing speech on men's potency.

He said by the "time you leave this seminar, men will have another 150,000 new sperm" to add to their male pride. Also the size of a man's testicles will have a proportionate and adverse effect on the size of his manhood. Something to do with chimps and gorrillas it seems.

But women it seems would have lost two to three eggs.

And the insurance angle? Answers on a postcard, please.
